Release Notes

gohugoio/hugo (github.com/gohugoio/hugo)

v0.151.1

Compare Source

This release is mostly motivated by some upstream security fixes:

• Upgrade from Go 1.25.1 to Go 1.25.3 which comes with 10 security fixes.
• Go's net/html package also has one security patch

I, @​bep, have inspected the above issues, and none of them seem to be relevant for Hugo, but we understand that many want to have a clean security report.

Bug fixes

• tpl: Fix strings/truncate CJK handling 88aea56 @​oishikazuo #​14039
• parser/pagerparser: Fix closing shortcode error handling when repeated a133393 @​bep

Improvements

• Upgrade Go to 1.25.3 e2fb0b0 @​bep
• create/skeletons: Wrap section and home lists with section tags 29cf874 @​imomaliev
• markup/goldmark: Align blockquote default output with Goldmark 1b4dd43 @​jmooring #​14046
• parser/pageparser: Store shortcode names as unique.Handle[string] to save memory allocations 4414ef7 @​bep
• testscripts: Make test assertion less specific 9197deb @​bep
